[−][src]Struct wasmer::Exports
Exports is a special kind of map that allows easily unwrapping the types of instances.
Implementations
impl Exports
[src]
pub fn new() -> Self
[src]
Creates a new Exports
.
pub fn with_capacity(n: usize) -> Self
[src]
Creates a new Exports
with capacity n
.
pub fn len(&self) -> usize
[src]
Return the number of exports in the Exports
map.
pub fn is_empty(&self) -> bool
[src]
Return whether or not there are no exports
pub fn insert<S, E>(&mut self, name: S, value: E) where
S: Into<String>,
E: Into<Extern>,
[src]
S: Into<String>,
E: Into<Extern>,
Insert a new export into this Exports
map.
pub fn get<'a, T: Exportable<'a>>(
&'a self,
name: &str
) -> Result<&'a T, ExportError>
[src]
&'a self,
name: &str
) -> Result<&'a T, ExportError>
Get an export given a name
.
The get
method is specifically made for usage inside of
Rust APIs, as we can detect what's the desired type easily.
If you want to get an export dynamically with type checking
please use the following functions: get_func
, get_memory
,
get_table
or get_global
instead.
If you want to get an export dynamically handling manually
type checking manually, please use get_extern
.
pub fn get_global(&self, name: &str) -> Result<&Global, ExportError>
[src]
Get an export as a Global
.
pub fn get_memory(&self, name: &str) -> Result<&Memory, ExportError>
[src]
Get an export as a Memory
.
pub fn get_table(&self, name: &str) -> Result<&Table, ExportError>
[src]
Get an export as a Table
.
pub fn get_function(&self, name: &str) -> Result<&Function, ExportError>
[src]
Get an export as a Func
.
pub fn get_native_function<Args, Rets>(
&self,
name: &str
) -> Result<NativeFunc<'_, Args, Rets>, ExportError> where
Args: WasmTypeList,
Rets: WasmTypeList,
[src]
&self,
name: &str
) -> Result<NativeFunc<'_, Args, Rets>, ExportError> where
Args: WasmTypeList,
Rets: WasmTypeList,
Get an export as a NativeFunc
.
pub fn get_extern(&self, name: &str) -> Option<&Extern>
[src]
Get an export as an Extern
.
pub fn contains<S>(&self, name: S) -> bool where
S: Into<String>,
[src]
S: Into<String>,
Returns true if the Exports
contains the given export name.
pub fn iter(
&self
) -> ExportsIterator<'_, impl Iterator<Item = (&String, &Extern)>>ⓘ
[src]
&self
) -> ExportsIterator<'_, impl Iterator<Item = (&String, &Extern)>>ⓘ
Get an iterator over the exports.
